TECHNICAL FIELD

The disclosure relates to wireless communications, and particularly to amethod and device for determining resources and a storage medium.

BACKGROUND

In a Fourth Generation mobile communication long term evolution (4G LTE)system, a user equipment (UE) always supports a system bandwidth of acarrier, and resource allocation is performed over the whole systembandwidth.

In a Fifth Generation mobile communication new radio air interface (5GNR) system, the system bandwidth of a carrier is dramatically increased(could be up to 400 MHz). A UE may merely support or merely need tooperate in a bandwidth much smaller than the system bandwidth.Therefore, resource allocation over the whole system bandwidthintroduces a too large signaling overhead.

In order to solve this problem, a legacy 2-step resource assignmentapproach may be employed as follows. In a first step, a “bandwidth part(BWP)” which is smaller than the UE supporting bandwidth is indicated;and then the detailed Physical Resource Blocks (PRB) are indicated overthe bandwidth part. And the bandwidth part is semi-statically configuredby the base station, i.e., gNB.

The legacy approach as described above has the following deficiencies:carrier aggregation (CA) will also be supported in the 5G NR system.However, the legacy approach cannot support CA operation. For a UE alsooperating in a secondary component carrier (CC), since the UE only hasthe Radio Resource Control (RRC) connection with the primary CC, theUE's bandwidth part in the secondary CC cannot be configured. Hence theUE's resource in the secondary CC can still be allocated over the wholesystem bandwidth. This results in an excessive signaling overhead inresource allocation for the secondary CC.

At block 101, a UE receives a first message over a first cell. Here, thefirst message is used for determining M first bandwidth parts (BWPs) ina second cell, M is an integer greater than or equal to 1, each of the Mfirst BWPs is smaller than or equal to a bandwidth of the second cell;and one or more transmission resources for the UE in the second cell iswithin at least one of the M first BWPs.

In the embodiments of the disclosure, the UE may be a mobile phone, alaptop, a notebook computer, a desktop computer or any device that cancommunicate with a network device.

In the embodiments of the disclosure, the UE may receive the firstmessage from the network device over a first cell. Here, the networkdevice may be a base station, e.g., a gNB in the 5G NR system.

In an implementation, the bandwidth of the second cell may be a systembandwidth.

In the embodiments of the disclosure, transmission resources in thefirst cell may be implemented by the first carrier, and transmissionresources in the second cell may be implemented by the second carrier.In an implementation, the first cell (i.e., the first carrier) may be amain cell (i.e., a main carrier), and the second cell (i.e., the secondcarrier) may be an auxiliary cell (i.e., an auxiliary carrier). The UEmay transmit signals in a carrier aggregation manner by using the firstand/or second cells.

In the embodiments of the disclosure, the UE may determine the M firstBWPs in the second cell based on the first message in the first cell, soas to transmit signals by utilizing one or more transmission resourceswithin at least one of the M first BWPs.

In the embodiments of the disclosure, the UE may determine the M firstBWPs in the second cell in the following ways.

Scheme 1: the M first BWPs are indicated by the first message, and theUE determines the M first BWPs based on the first message.

For example, 3 first BWPs, i.e., BWP1, BWP2, and BWP3 are indicated bythe first message, and the UE determines BWP1, BWP2, and BWP3 based onthe first message.

Scheme 2: N second BWPs are indicated by the first message, N is aninteger greater than M, each of the N second BWPs is smaller than orequal to the bandwidth of the second cell, and the UE receives a secondmessage over the first or second cell, wherein the second messageindicates the M first BWPs among the N second BWPs.

For example, six second BWPs, i.e., BWP1, BWP2, BWP3, BWP4, BWP5, andBWP6 are indicated by the first message, the second message is used toindicate three BWPs, i.e., BWP1, BWP2, and BWP3 among the six BWPs. TheUE determines BWP1, BWP2, and BWP3 based on the first message and thesecond message.

In an implementation, the first message may be conveyed by RRC signalingor system information (SI).

It is to be understood that if M=1, the first message containsinformation about configuration in one first BWP; if M

2, the first message contains information about configuration in allfirst BWPs. In this way, the UE can determine information aboutconfiguration in the first BWPs based on the first message and performsignal transmission over the transmission resources within the firstBWPs based on the information about configuration in the first BWPs.

In an implementation, the UE receives a third message over the first orsecond cell, where the third message indicates the one or moretransmission resources for the UE within the first BWPs of the secondcell. Here, the transmission resources for the UE are time-domainresources and/or frequency-domain resources for the UE, and the UEperforms signal transmission within the indicated transmissionresources.

In an implementation, the third message may be conveyed by the DCI orthe MAC CE.

In some embodiments of the disclosure, the first message may betransmitted over the first cell, the second message may be transmittedover the first or second cell, and the third message may be transmittedover the first or second cell.

In an implementation, if the second message is transmitted over thesecond cell, the second message is transmitted by using the transmissionresources within the first BWPs.

In an implementation, if the third message is transmitted over thesecond cell, the third message is transmitted by using the transmissionresources within the first BWPs.

-   -   1) By cross-carrier configuration of a bandwidth part, resource        for a UE in a second carrier can be allocated over the bandwidth        part with a much smaller size. It can significantly reduce the        complexity and signaling overhead for resource allocation. Hence        it enables a UE to perform an efficient carrier aggregation        operation in an ultra-wideband system e.g. 5G.    -   2) Furthermore, it also supports dynamic selection of bandwidth        part by the second carrier from a set of candidates        pre-configured by the first carrier. This keeps the flexibility        of bandwidth part configuration in case no perfect backhauling        supporting dynamic signaling exchange exists between the two        carriers.
